Taipan veteran leak

Hello, i bought a taipan veteran a few months ago and shot a little over a thousand pellets through the gun flawlessly with no issues besides my gun not tuning properly (50-60 fps deviation per shot if not on max power). Well i've been pretty busy the past 3 months so i put the gun in my safe at 230 bar, and today i decided to pull it out and make sure everything was good to go and my gun was at 0 bar and has leaked all the air out. I'm not really sure what to do or if my gun has a leak, my marauder has been sitting at 2500psi for a 4 months and hasnt moved.
 
It's definitely leaking its dropped from 250 bar to about 230-235, I think this has something to do with my regulator because when i first bought this gun and just SLIGHTLY tried tuning the power adjuster down to shoot 25gr pelets i would get insane deviation upwards of 80-100 fps difference almost every shot would be 900 then the next 800 with audible power difference each shot and almost 2 inch point of impact shift. I contacted utahairguns when i first got the gun about the issue but seemed like they were not much help
 
Now that i have time to shoot again coming up ive been thinking hard about sending it off to someone who knows what they are doing and tune the gun and fix the issues im having because this is only my second pcp but this one costing me so much money id rather not mess up anything, its still basically brand new its unfortunate im having so many issues
 
Had the same issue with a Taipan Veteran Long .22 recently, less than 2 months old. Leaked down to 0 overnight from 200 bar. I suspect it was a regulator issue. Sent it back to the supplier and never did get it repaired, tried to sell me a new regulator. Turned into a pissing contest. Thankfully I received a full refund. Shopping for a new airgun at the present time.
 
Just an update, it has leaked, went from 250 to 80 bar since making this post. I'm not sure if i can get a refund since i drilled and tapped the wood stock for a bipod mount. I think the only option is send it for warranty work which i wanna avoid from past warranty claims that took almost a year to get my stuff back. I'm in GA so maybe i can send it airgunsofga to see if they can fix it or somewhere else that does work on them. I'm 99% sure its a regulator issue based on the issues i had tuning the gun, at this point i might even try and fix it myself and order a huma regulator and follow the guide on youtube doesnt look as bad as i thought honestly.
